What is the constellation of 65438+February 2 1?

Capricorn is also called Capricorn. Among them, 65 stars are brighter than Grade 6, but the main stars are all Grade 3-4, which is the second faint zodiac (the darkest zodiac is Cancer). Unlike most constellations, the brightest star in Capricorn is not its alpha star, but its delta star, which is slightly brighter than Chinese level 3.

Every year at midnight on August 8, Capricorn reaches the zenith. In the southern night sky in August and September, the weather is fine and the light pollution is weak. Observers in the middle and low latitudes in the northern hemisphere can see the dark Capricorn on the east side of Sagittarius. Extending from Vega to Altair about 1 time, you can see two third-class stars, which are the heads of Capricorn.

Study history

Capricorn is also related to a story in astronomical history. Astronomers observed that Uranus was disturbed in its orbit around the sun. After calculation and observation, Neptune, the eighth planet in the solar system, was discovered in A.D. 1846, so Neptune is called "the planet found on the tip of a pen". Neptune was in Capricorn.
